Proper synchronisni is maintained between the repeating apparatus andthe distant rotary distributor or fork by means of correcting-relays CRand CR The vibrating tuning forkTF controlling the opera- ;tion ofphonicmotor PM is adjusted to vibrate slightly faster than the distantsending fork or distributor, and by operation of V the correctingmechanism is corrected to run fin contact '8 since the current throughwindingW overpowers the lesser current in winding On the other hand, ifthe circuit through winding W is not completed through a segment ofrotary commutator RC at the moment the tongue of relay GR is passingacross its gap, the winding "W ofrelay CR will not be energized, and thetongue of relay CR will be operated to its marking contact by currentflowing through winding VV The slowing-down circuit thus completed fromnegative battery to the magnet of the fork, causes the fork to besuddenly arrested because of the increased field strength, and the forkis slowed down. Accordingly, if when relay CR operates, the circuitthrough-winding N is not completed through rotary commutator RC therelay CR will be operated to its marking con tact M and will slow downthe forln. If

when relay GR operates, the circuit throu h B through the operation ofworm 46 (see Fi By this means the operation of the relay may beproperly' iphased with respect to incoming-s gnals V c ln case it .bedesired to einployfthe regenerative repeater for the transmission oftelegraph signals fromithe tape transmitter' TE, the transfer switchSl/V is thrown to the; dotted line position shown .in Figure l,lviththis circuit arrangeinent, the dot the tape transm tter controlregenerative "action of the repeater is the same asv described above.The operation ofcuit from terminalto terminal transmitter TB ismaintained in synchronism with the synchronizing impulses transmittedover the incoming cable 0 sincethe operating cam 18 of thetransmitter isdriven from the same shaft hich drives rotary commutators RC and RC Fromthe foregoing, itlWill I- have devised a system in which regenera-- tiverelay may be employed'foirepeating signals from one cable to another, orfor transmitting signals from 'a tape transmitter at'the relay station.It- Will also 'be'seen. that I have devised means for keeping thecircuit in synchronism, that is, the Whole cire While the re generatorat agrepeating stationisbeing I used for transmitting'purpo'ses.
